Trust me, jelqing and certain other PE's WORK! I was 6 inches and went to 9 in about two years (it takes a long time).
1. Pumped with an electric powered Dr. Kaplan pump, which loosened my suspensatory ligaments ( the key to length; that gremlin rope between your balls and asshole IS COCK; some say the difference between one cock size and another is how tight the suspensatory ligs are).
2. Did the Matters Of Size exercises. Awesome!
3. Hung a weight around my dick for a few hours a day.
4. And finally, used the Max-Xtender while sleeping.
You can do it!
